STORM INFORMATION
AT 2 PM CHST, THE CENTER OF TYPHOON SINLAKU (04W) WAS LOCATED NEAR
LATITUDE 10.2N AND LONGITUDE 151.0E. THIS WAS ABOUT 470 MILES EAST-
SOUTHEAST OF GUAM. STORM MOTION WAS NORTH-NORTHWEST, 345 DEGREES, AT
9 MPH. STORM INTENSITY WAS 125 MPH.
SITUATION OVERVIEW
TYPHOON SINLAKU (04W) IS SLOWLY MOVING AWAY FROM CHUUK STATE, AS IT
REDIRECTED TO THE NORTH-NORTHWEST AND CONTINUES HEADING TOWARDS THE
MARIANAS. IN THE MEANTIME, SINLAKU CONTINUES TO BRING PERIODS OF
INTENSE SHOWERS, THUNDERSTORMS, AND WINDS TO A LARGE PORTION OF CHUUK
STATE, PRIMARILY TO ULUL AND FANANU. RECENT STORM TRACKS PRODUCED BY
JTWC CONTINUE TO SHOW A MORE NORTHWARD SHIFT IN THE STORM PATH
DURING ITS PASSAGE TOWARD THE MARIANAS, NOW EXPECTED TO CROSS
SOMEWHERE BETWEEN ROTA AND SAIPAN. EVEN SO, IT IS STILL TOO EARLY TO
PROVIDE EXACT WIND AND SURGE FORECAST VALUES FOR ANY SPECIFIC ISLAND
IN THE MARIANAS.
PRECAUTIONARY/PREPAREDNESS ACTIONS
FOR THOSE UNDER A WARNING, NOW IS THE TIME TO RUSH TO COMPLETION
PREPARATIONS FOR THE PROTECTION OF LIFE AND PROPERTY. EVACUATE IF
DIRECTED TO DO SO BY LOCAL OFFICIALS, OR IF YOUR HOME IS VULNERABLE
TO HIGH WINDS OR FLOODING.
IN ORDER TO MAKE THE BEST DECISIONS, BE SURE THAT YOU UNDERSTAND THE
TERMINOLOGY AND DEFINITIONS ASSOCIATED WITH TROPICAL CYCLONE EVENTS.
STAY INDOORS DURING HEAVY RAIN AND WINDY CONDITIONS ASSOCIATED WITH
TYPHOON SINLAKU (04W). THE ONSET OF DAMAGING, AND POTENTIALLY
DESTRUCTIVE WINDS, WILL POSE A DEADLY THREAT TO THOSE VENTURING
OUTSIDE.
FOR ADDITIONAL PRECAUTIONARY AND PREPAREDNESS INFORMATION, PLEASE
REFER TO THE DETAILED RECOMMENDATIONS RELATIVE TO YOUR LOCATION AS
FURTHER DESCRIBED BY YOUR LOCAL NATIONAL WEATHER SERVICE OFFICE AND
YOUR LOCAL EMERGENCY MANAGEMENT.

..WIND INFORMATION
AS TYPHOON SINLAKU (04W) MOVES CLOSER, THE THREAT FOR SUSTAINED HIGH
WINDS WILL CONTINUE TO INCREASE. TROPICAL STORM FORCE WINDS ARE
CURRENTLY FORECAST TO BEGIN AFFECTING GUAM LATE MONDAY AFTERNOON,
ESPECIALLY NEAR THE NORTHERN COASTAL WATERS AND SHORES OF GUAM COMING
INTO TUESDAY.
..COASTAL INUNDATION AND SURF INFORMATION
DUE TO HIGHER ASTRONOMICAL TIDES THIS WEEK AND PRE-EXISTING ELEVATED
SEAS DUE TO NON-TC FEATURES IN THE AREA, HAZARDOUS SURF IS LIKELY TO
BECOME DANGEROUS ACROSS NORTH, EAST AND SOUTH REEFS IN THE MARIANAS
AS SURF BUILDS TO 15 FEET TONIGHT, AND POTENTIALLY SPREADING TO WEST
FACING REEFS ONCE TY SINLAKU MOVES WEST OF THE ISLANDS IN THE NEXT
SEVERAL DAYS. COASTAL INUNDATION IS BECOMING MORE LIKELY, NOW
POSSIBLE AS EARLY AS MONDAY MORNING; AS SUCH, A COASTAL FLOOD WATCH
REMAINS IN EFFECT BEGINNING MONDAY MORNING FOR SIGNIFICANT COASTAL
INUNDATION OF 2 FEET OR MORE POSSIBLE. INLAND FLOODING MADE WORSE BY
DEVELOPING RAIN BANDS DURING STORM PASSAGE WILL SIGNIFICANTLY
INCREASE COASTAL INUNDATION AS RAIN RUN-OFF AND STORM SURGE INTERACT.
SURF WILL BE SLOW TO DECREASE AFTER SINLAKU'S EXIT TO THE NORTHWEST
IN THE SECOND HALF OF THE WEEK, AS SWELLS WILL CONTINUE TO PUMMEL
WESTERN MARIANAS SHORES.
..OTHER STORM EFFECTS
HEAVY, INTENSE RAINFALL WITH TY SINLAKU IS LIKELY FOR MUCH OF THE
WEEK, WITH RAINFALL AMOUNTS UPWARDS OF 15 TO 20 INCHES NEAR THE
CENTER, AS THE SYSTEM CROSSES THE MARIANAS. THE EXACT TRACK OF
SINLAKU WILL DETERMINE WHERE THE HEAVIEST RAINFALL WILL SET UP
ACROSS THE ISLANDS. AS SUCH, A FLOOD WATCH REMAINS IN EFFECT FOR
GUAM. SEE LATEST FORECAST FOR LATEST INFORMATION. LISTEN FOR
POSSIBLE FLASH FLOOD WARNINGS FOR YOUR LOCATION, AND BE READY TO
ACT IF FLASH FLOODING DEVELOPS.
